FAQ

Q: Could you provide free samples?

A: We can offer samples for free, but the shipping cost shall be negotiated by both sides.

Q: Can I use hex nuts with any bolt?

A: Hex nuts must match their bolt's specifications exactly - including thread size, pitch, and grade. Using mismatched fasteners can lead to connection failure.

Q: How do you prevent thread galling or seizing when using stainless steel hex nuts?

A: Thread galling is common with stainless steel fasteners during high-speed installation. We mitigate this by manufacturing with precise thread tolerances and offering specialized anti-galling wax coatings or lubricants (such as molybdenum disulfide or teflon-based coatings) upon request to significantly reduce friction during assembly.

Q: Can your factory supply hex nuts that meet specific automotive torque-tension coefficients?

A: Yes. Under our IATF 16949 quality framework, we can strictly control both the heat treatment hardness and the surface finish chemistry (including applying specific friction modifiers or topcoats).

Q: Can hex nuts be used outdoors?

A: Yes. Stainless steel and hot-dip galvanized options provide excellent corrosion resistance.
